To all whom 'it may concern Be it known that I, CHARLES H. HUNTER, acitizen of the United States ol America, residing at clarrisburg, in thecount)Y of Dauphin and State or' lennsylvania7 have invented certain newand ments in Combined T ypc-llVriting and `omputing Machines. of whichthe following is a specification.

My present invention relates to billing machines of that class which ischaracterized by writing mechanism combined with computing devices whicheffect mechanical computations as the elements thereoiC are written andrecorded.

The object of the invent-ion is to produce av machine adapted tofacilitate accormting operations byI relieving the operator of thenecessity for mental calculation and by me chanica'ly proving orchecking the result of each operation accon'iplished.

More specilically stated., a primary object of the invention is toprovide means whereby the bill or statement may be made out and theledger simultaneously posted, after each transaction or series o1"transactions,

and the condition of the account, with ertended balance or total7constantly showir and mechanically checked or proved, the ultimate endattained being the proving or checking of every operation and thesecuring of a complete statement of the exact condition of the accountafter each debit or credit posting,

To the accomplishment ol the object stated, one cml'iodiment of theinvention rcsides in the construction and arrangement Shown in theaccompanying' drawings and hereinafter .fully described.

ln said drawings z-s- Figure 1 is'a plan view oi" an Elliot-t- Fisherbilling machine equipped in accordance with my invention.

2 is a rear view oi a portion ol th'.- carriagev of the machine shown inFig. l.

designed more particularly to show thc rclative locations ot the masterwheels ot' the triplex actuator and the resetting cams Ator theregisters.

Fig. 3 is a sectional end elevation ot' the machine.

Fig. 4 is a diagrannnatic view designed to show the arrangement of theprinted record useful Improve- D for the performances of one oi' thehillii and also to make clear the manner in which the .respectiveregisters are appropriated to the various'portions or columns ot' therec-- ord.

Figs. 5, (5, 'l" and 8 are diagraunnatic views of the different relativepositions assumed hy thel actuator with respect to the registers duringa debitposting.

Fig. 9 is a diagrammatic view showing the registers positioned for acredit posting, and

Fig. l0 is a diagrammatic view showing step by step the results ofposting operations.

lt may be stated, by way olf' premise, that the machine,'which forpurposes of illustration l have shown equipped with my invention, iswhat is known to connnerce as the Elliott-Fisher billing' machine. Thegeneral and well known characteristics oi this machine will be brieflydescribed.

The llllliottlfisher machine, includes a fiat platen l over which amachine trame 2 travels longitudinallj,Y for line spacing. The frame 2supports a carriage 3 movable transversely of the platen ior letterspacing and this carriage in turn supports downwardly acting printingdevices l, operated by letter and numeral keys 5 and (3 through suitableintermediate connections. ln addition to these features are the variousadjunctive mechanisms of fiat platen tvpewriters.

In addition to the typewriting mechanism, the machine embraces computingmechanism which is operated from numeral keys of lthe typewriter.Supported in rear o1"l the carriage 3 on brackets 7, attached to theframe 2, is what is known as a register -bar 8 disposed parallel withthe path of travel oic the carriage 3 and adapted to support one or moreregisters 9, each embracin a series or" denominational members 107suitable carrying mecluinism (not shown) and various other structuralfeatures. the specific character of which are not material to this disclosure. These dcnominatioiml members 10 arc spaced to correspond withthe letter since advance ol the carriage and are designed to be operatedby actuating mecha nism including a master wheel llpmounted on andmovable `with th carriage 3 to suclll) .actuator so amplilied "oy theaddition vis rotated hy cach of the numeral keys, a

munher of increments or units of movement corresponding to the value ofthe particular key operateil. lt will thus he Seen that thedenominational position of the master wheel with respect to the register'is determined by the position o1" the carriage, so that thedenominational member operated` will correspond in denominationalposition to the deiioii'iinational position in which a. digit is printedin the column. it will be equally clear that the extent or Value of theoperation of the denominational iiieinher so eelected will correspondwith the Value of the particular hey depressed and the particular diojitprinted.

As is clearly shown in the patents to which attention has heen directed,it is quite common o provide the register bar 8 of the billing machinewith any num'her ot' registers 9 appropriated lio dil'erent columns sothat when the typewriter is in position to print in any one of severalcolumns, the master wheel il will he in. position to operate 'in one ofseveral registers, so that one or ymore columns ma)y lie inmhanicallyadded.l as the record is iiiade by the machme.v in.

accordance with my inventiomhowever, the of supplemental master wheelsand the 'tei are so rclativelidisposed, that in those types ot hillingoperations with which the invention is concerned, certain registersoccupying di"}rcnt column positions will he simultaneously operatedduring the printing` or a iiuiiihcrin a colunm under certainconditioiror operated independently under other conditionst Vstill otherregisters being operated to etl'cc entirely independent coin--piitations, ln other words the registers and the actuating;mechanism areso related that., while tei-tibi registers are entirely independ ent inthi-ir operation, an interrelation will exist lietii'4 en diecomputations of other isters so that a proof, or check may be secured hythe mechanical inclusionin one register of the. sum of the rceultssecured in other registers, the registers last named licinpf thus madeto show totals :if dii'fcreut import which. when combined. must equaltue total shown hy another register if the operation :ias been performedcorrect i To he more explicit, 'l exiend the main shaft i3 of thezwtiiatorl beyond theiight hand end of the carriage 3 and attach theretotwo additionrl master ii'heele Mand l5 spaced a pa rl. just sullicicntlyto prevent ho'th ot' said master wheels-troni engaging a regristcr atthe same time. hus when the pri mary master wheel ll is rotated in 'theusual providing the same with duplications of the safely devicesordinarily employed in conneclion with the primariv master wheel. Inaddition to this triplex or three wheeled actuator, l so dispose aseries of tive registers',

A, B, C. l), and ll on the bar S that the li'rst and third rcistei-s.lto-wit, A and C5 may he operated in correspondence when a num'hcr isprinted in a column to which `the (ii-st register ii is appropriated.The relation oft' thc registers also permits theisecond register lf3 andthe lourth register D to he operated independently' or each other and ofthe other registers hut compels the siiiiultancous operation of thethird register C and the lil'th register E iihcnever a munher is printedin a column lo which the register C ie appropriated.

'thus in the diagrammatic Fic'. l ot' the drawings is shown a ledgershe-et and :i supcrposed statemcutdesigned lo receiveJ simultaneously`the record produced li'v the posting operation. At the lel't hand sideof the statement is a column marked f (lld halance,-to which theregister A is Yaliproiifiated. To the right of this coluiiin'is theusual space for the number and date; then a space for the entryiofitem55.` e'xt is an item or detail columinto which the iegistei;

is appropriated. Next is the debit eolumn, to which the. register C isappropriated. Next is the credit column to which no regie4 ter isappropriated because. i'n 'this diagrainl matic showing, the machine is.set for deliit posting. To the right of the credit column is' the newbalance column to which the register D is appropriated. The register ismer el}v a proof or check register and. loi'responds to no column on thestatement.

Let us assume that the current or' old bal-I ance ot' the customerywhose account is to he posted, is $25.50, as shown in Fig.- 10, andJdial a debit posting to be made. The operator first prints the oldbalance -in the old balance column and as he does so, it will he seeinhy reference to Fig. that the amount $25.50 is Set up in each ot' theregisters' andC. to wit, the old balance register and the debitregistri; Next the operator proceedsgi a detail posting' is in order, toprint theklcbit items in lhe item column, the items slioii'ii in Fig.10. heilig.

i im mi $1.50 l vFancy 4. l Buckle- L 5. 50

These amounts will now have been accumulated iii thil item register B hythe opera iion o'l' lhc primari' master wheel l1 andis'fioo theauxiliary master'wheels are not opposite registers, this operation ofthe register B will be entirely independent. The total of the debititems thus accumulated, to Wit. $11.50, will now be displayed in theregister B and will be copied therefrom into the debit column, see Figs.7 and 10. This act will accomplish two results aside trom the printingofthe total debits in the debit column. First, it will add $11.50, theamount ot' thc total debits posted, to the old balance ($25.50) alleadYin debit register C, thus causing said register (l to display a newtotal or balance of $37.00. Second. the act ot' printing #ne debit totalin the debit column will accumulate thel amount of such debitl total, towit., $11.50. in the prootl or cheek register E be.- cause. as shown inFig. 7. the auxiliary inas ter wheel 15 will he in coperation with theregister E during this o )eration ot printing the total .debit in thedebit column. `Now then` register A will show the old balance ot'Register B will show the total debits ot' this particular posting.$11.530.

Register C will show the sum ot the old balance and the total debits otthe current posting, to Wit, $37.00, and the check or prooi register Ewill show the amount ot the total debits, to wit, $11.50. The checkregister 'E will now be seen to afford a check or proof ot' theaccru-ac)Y oie the total debit extension because, the act of printingthe total debits is the act which set up the register E. and it theoperation was accurate, the register l must 'of necessity correspondwiththe total accumulated in the item register ll during the printing ofthe debit items. Rut that is not all because a further cheek is provided by the fact that the debit accumulation in the register E, plusthe old balance shown in register A, must equal the new balance inregister C. This last named rel .n will be seen to properly check theoperation when skeleton vposting instead ot detail posting is desired',because it we eliminate detail register B and the detail debit column,the safeguard afforded by the corresponding registers B and E is notobtained but an absolute check is, nevertheless, atlorded by the. tactthat the amount accumulated in the debit register (l must correspondwith the sum of the amounts accumulated in registers A and E. Having nowascertalined the amount. to wit, $37.00, accumulated in the debitregister (l, the operator copies this amount in the balance column andaccuniin lates it independently in register D. (See lfig. 8). Thisamount, $37.00. now becomes the current or old balance with which thenext posting operation is to start and the operator, after clearing theitem debit register B and the total debitrcgister (l. pio ceeds with hisnext debit posting in the inanner just described. The registers ft. l)and IC are not .cleared because, the balance increases with eachposting, so also inust the old-balance and the total debits be anded inthe registers A and .E resi'iectirely, so to perpetuate the prootlafforded by the re quirelnent that the sum of the amounts regs tered hvthe old balance register il. and the proof register l@ must always equalthe amount accumulated in the balance ter D.

lt has already bee'n stated that the detail or item register B may beomitted, though it is desirable to employ this register in order tosecure accuracy'fiu the addition ol'v the debit items. There are othervariations also which will readily suggest themselves. l. 'u' instance.in retail department store work, where customers trequently buf.7 insevera1 departments and thus cause several separaLd is ne'r cleareda'ttcr the entl f et each ticketbut caused to accumulate all itemsptu'chay al.

The etl -r Y ters tl. D and lll re'iain theoriginal ch acter` the register t being cleared. attereeWl postingoperation and the registers ./'l and lll cheri-:ing against the registerD.

lu credit posting, the genoial character or operation is the same as` indebit pos' f. with 'the same mechanical checks 'itfaiwf error but theoperation of subtract. to deducty the credit trom the balance isaecomplished by what is known as coniolenentai addition, an operationtoo well known to require specifi explanation. 'The method ot operationin making a credit posting will,

Preliminary tothe credit posting all registers are Cleared, the debit item4 register'B is eliminated and the register C, which will now he utilized toaccumulate. credits negatively as subtractions from the old halanee,will he shifted along' the renie-ter hair to a position corresponding to'che position of the credits Column on the statement. (See Fig. Q). Thetaoulating n'rechanism of the typewriter will, of course, becorrespondingly reset.

The first operation is to Write the old hal ance, for instance, $48.50,in the old balance column which. will Cause this nurnher to he set up inregisters A and C by the master wheels ll and l5. Next we subtract hyeoinpleniental addition by printingr the credit posting of $25.50 in theCredit column which adds the complement ot $25.50, kto wi 99974.50 incredit register C and also in,

Acheck r proof register E. lt must he vineeabered, however, that theregister (l has already accunnilatetl the old balance7 to wit.lill-8.50, and hy reason ot the addition toereto on the coinpleinent,will now read 5523.00, which is the new balance. This new balance nowwritten in the halai'lce column and accumulated in balance register D,just as in posting the dehits. The register C is now cleared before the`inz'iohine is returned for a new line, and the described operation isrepeated in the posting of succeeding credits.

Register E, while posting' credits, always shows the complement ot thetotal credits. For instance, if total credits ot 95561.82 have heenposted. register lil will read 99438.18. Likewise, when 'posting aCredit to an acH count hayingf a` delnit balance less than the amount olthe credit -posting, the computingr register (l will show thecoiniilen'ienl' ot the Credit halancc. ll`or instance, if a credit ol ishosted to an account haringT a dehit halance of $924, credit register Cwill read 99983.59. ln credit posting, the same character oil prooi issecrn'ed as in dehit posting` lic-,cause the new halance shown hy creditregister C, plus the complement et the minus quantity shown in registerE must equal the old balance and 'it desired. the 4minus quantity shownin they check or proof reg istcr E, inay he prored l y adding' theretothe amount of the credit cntry which should result in 4("learingl theregister E. This last named @aeration ot clearingY the register l isordinarily accomplished hy vthe inanipu lation ot the non-print keys (inwith which thc billing' nnu-hine is ordinarily prorideil, shown inlatchts 92,8654 to ll.

For the purpose or' the present disclosure, l. have considered ii;necessary to describe in detail only the inode of operation of themachine in the posting of debits and credits and the extension of thebalance a''ter each entry. lt will he understood, howereigthat themachine is susceptible to niany other modes ot' operation in connectionwith other 'tornis of accounting and in 'posting to aecounts of varying;conditions. In all eases, however, Athe underlying principle ofOperation is the saine and in all cases prooi' is secured. For instance,in posting a charge to an aeeount already showinT a debit balance, theproof is that the old balance plus the debit posting, must equal the newbalance.

In posting a charge to an account showing an old credit hal ance, whichis greater than the charge posted, resulting in a new credit halance,the proof is that the old balance shown coinpleinentally plus the Chargeposted, must equal the new balance also refbristered` Coinplenientally.

.in posting a charge to an account haw ingr an old Credit hal ance lessthan the amount et the charge which results in a new debit balance, theprooi is that the old balance expressed cmnpleinentally, plus the debitposting must equal the new balance.

In posting' a credit,to an account having an old debit halance greaterthan the credit posting vwhich results in a new debit balance, the proofis that the old balance, plus the complement oi credit, must equal thenew balance.

In posting a credit alteran aeeount with a debit balance than the creditposting which results in a new credit balance, the prooi" is that theold balance plus the com pleurent oi' the credit posting, equals theci'nnplenient or the n fw credit balance.

ln posting a credit to an account with an old credit balance which, ofcourse, result-s in a. new credit balance, the proof is that the oldbalanceexpressed coniplcmentally,

plus the credit posting, expressed coin plcnunally, must equal the newlmlance, the complement also or which is registered.

lt may hc stated in pass" j that all del its, whether old balance,posting or new halance. appear in black, are n'riiten and addedT and allcredits, whether old credit lnilance, posting or new credit balance.,are written in red and arc always subtracted and printed.

lt may also he, stated in passing that where auxiliary master wheels areclniloyed, as herein' shown. it is desirable to employ a plurality oirestoring canls Y, (see Fig. 2) 'lor the carrying or transfer devices ofthe registers. This duplication el the singlev rester-inir canlordinarily employed is'not al solutely necessary hut it avoids thenecessity for moving the carriage a suilicient distance to the right toplace the single cani in position to restore all registers as theCarriage is ri traeted.
